Change to the following....
Text Formatted Code
$_DB_name = 'brlmedia_geek'; // name of your database,
// must exist before running the installer!
$_DB_user = 'brlmedia_geek'; // MySQL user name
The prefix is added to your table names, not your database name. I'd change your prefix to something shorter than 'brlmedia'...makes using MySQL much easier
